IMPROVEMENT IN FOLDING CHAIRS.

Specification forming part of Letters Patent N0. 190,974, dated May 22,1877 application filed December 11, 1876.

To all whom it may concern Be it known that I, EUGENE H. MAHONEY, ofBoston, in the county of Suffolk and State of Massachusetts, haveinvented certain Improvements, new and useful, to Folding Chairs, whichare fully set forth in the following specification, reference being hadto the accompanying drawings.

This invention relates to certain improvements of the chair patented byGeo. G. Paine, September 19, 187

Figure 1 is a side elevation, partly in section, of the chair set up foruse. Fig. 2 is a front view of the chair, and Fig. 3 represents itfolded.

This chair is constructed substantially like the chair as referred to inthe patent of Geo. G. Paine, before mentioned, except that the lowerends of the posts 19 of the back-frame A are connected to the legs I atthe point where the legs cross each other by a pin, a, which passesthrough the lower end of the posts 19 of the back-frame, and alsothrough the legs I, where they cross, thus serving the double purpose ofsecuring the lower end of the back-frame A to the legs l, and also as apivot to unite the legs, and upon which they turn. The back-frame A issecured to the upper ends of the front legs on a level with the seat, bya pin or screw, 0, which passes through the posts p of the back-frame,and into the end of the back-rail of the seat. The pin or screw 0 doesnot act as a pivot in any manner.

By this mode of construction a back is provided for an ordinarycross-legged campstool, rendering it a very cheap, simple, andconvenient chair.

I claim- The combination, with the cross-legs Z, of the back-frame A,the side posts 10 of the back-frame being rigidly secured to thebackrail 6 of the seat at the upper ends of the front legs, andconnected to the cross-legs at their points of intersection by a pin, a,which forms a pivot for the legs, as set forth and described.
